The staff at William Standen Co were excellent to work with. Always patient, kind and very knowledgable. They kept me updated in all that was going on with a weekly review and answered any additional questions without hesitation. The workers left the work site neat and tidy everyday. I enjoyed watching the addition at all stages and was always interested in each step. The addition turned out exactly how I envisioned it and am very happy with the results. A great team to work with.

Freya Bartelen

William Standen completely redesigned our dining room, living room and kitchen into one open concept kitchen/living space. We could not be happier with results. Cassandra and Patrick were excellent to work with and truly care about the quality of work from design to finished product. Every person who worked on our project was kind, courteous and worked to a high standard. The result is a living space that we truly love and enjoy. We would not hesitate to hire this company again in the future. A very positive experience for our family.

Michael Moloney

William Standen provided design and project management services to us. They were the company we selected to renovate our kitchen. They completely gutted our kitchen including ripping out flooring throughout most of the upper part of our house including stairs. The products and services they provided were top quality. Both Cassandra & Patrick were extremely knowledgeable about all the products & services they provided. We really felt they cared about the work they were doing at our house. The job was completed within the specified time frame. They communicated frequently with us on the status of the project and if they had any questions or concerns, they notified us quickly. We highly recommend them.
